spi: nxp-fspi: reset the FLSHxCR1 registers
Reset the FLSHxCR1 registers to default value. ROM may set the register value and it affects the SPI NAND normal functions. Signed-off-by: Han Xu <han.xu@nxp.com> Link: https://lore.kernel.org/r/20230906183254.235847-1-han.xu@nxp.com Signed-off-by: Mark Brown <broonie@kernel.org>
